MECHANISM FOR OPERATING SAUSAGE-STUFi-'l lvlACHlNES.

SPECIFICATION forming part of Letters Patent No. 359,971, dated March 22l 1887.

Application filed January 19, 1886.

To @ZZ whom it may concern:

Be it known that l, Gus'rav ADoLri-i Horr- MNN, of Milwaukee, in the county ofMilwaukee and State of W'isconsin, have invented certain new and useful Improvements in Mechanisms for Operating Sausage-Stuffing Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a partof this specitication.

My invention relates to that class of sausage-staining machines in which the piston is driven by steam or other power. Y

It consists, essentially, of friction driving mechanism suitably geared or connected with the piston and of an automatic stopping device. Its objects are, first, facility and rapidity of operation; second, economy of labor, and, third, a variable feed under the constant and instant control of the opera-tor, whereby a great saving is effected in cases and the work more perfectly done than is possible with a regular invariable feed. These obj ectsl attain by the mechanism hereinafter specically described.

In the accompanying drawings like letters designate the saine parts in the several figures.

Figure l is a plan view of the machine, portions of the piston-rod or rack-bar being cut disclose the automatic-brake attachment. 2 is a side elevation; Fig. 3, an end elevation; and Fig. 4 is a longitudinal vertical section of the rack-bar and underlying brake-bar with the driving-pinion shown in side elevation.

A represents the frame-work oi' the machine, formed of any suitable material-preferably cast-iron-and of the desired shape to support the various operative parts of the machine and furnish bearings therefor.

C is the piston, closely iitted by suitable packing to the inside ofthe meat-cylinder K, supported at the middle by trunuions in said framework A, so as to be readily swung from a horizontal or Working position into an upright position for being redlled. It is secured in its horizontal or working position bythe Serial No. 159,094. (No model.)

counterweighted catches a a, pivoted to the frame A, and by the ears o', formed upon said cylinder and resting upon said frame A.

The piston C is secured to or formed upon the end of the rack-bar B, which is supported and arranged to move horizontally in bearings b b in crosspieces of frame A, and recessed upon its under side to reduce its bearing-surface and to receive the brake bar I, placed underneath it.

The parts thus far described are common to machines of this class, and may be of the ordinary or anysuitable construction and material.

Upon a lateral'cxtension of the frame A is mounted the longitudiDaily-sliding frame N, provided with bearings for the shafts m and a. Upon the shaft 'm are secured the friction-wheel D, inside ofthe frame N, andthe small pulley H, outside of said frame, and upon the shaft a are secured in like manner a smaller friction` wheel, E, in line with said friction-wheel D, a pulley, F, inline with and considerably larger than said pulley H, and thedriving'pulley G, connected Witl'1suitablepower.` Between and in line with said friction-wheels D and E the main driving friction-Wheel O is mounted upon the shaft o, which is journaled in fixed bearings i'ormcd ou frame A. To the end of said shaft o adjacent to rack B is attached the pinion @,so as to mesh with the gear d, of greater size, mounted upon shaft la, which also has iiXed bearings in frame A, and is provided With a pinion, c, meshing in turn with the large gear f on shaft t', which bears the pinion g, engaging and driving the rack B. The several gears and pinions interposed between the friction-wheel O and the rack B are so proportioned as to drive said rack and the piston C with the desired force and rate of speed in its advance movement when the frictiomwheel O is driven at a certain rate. A cross-belt connect ing the pulleys F and H drives the frictionwheel D in the opposite direction from the rotation of the friction-wheel E and at a much greater speed.

A lever, M, fulcrumed to the frame A of the machine, is connected by its shorter arm with frame N by means of an ear, s, projecting therefrom, as shown in Figs. l and 3, and by its longer arm, by means of the rod Z,witl1 ICO mounted thereon by the foot, thus freeing the hands of the operator for manipulating the cases on the gut-tube a of the meat-cylinder l K, I provide the lever L with a cross piece or arms, 1 7', the ends of whichjare connected by cords or chainspp with the foot-lever I), pivoted between said cords p p to the floor.

The rod I, supported in boxes b Z on frame A in the longitudinal groove or recess in the rack-bar B, as shown in Figs. l and 4, is connected with the lever llLas seen in Figs. 3 and 4, projecting a little beyond or to the rear of said lever at one end,and beyond or in advance of the box b at the end adjacent to the piston C. The' rack-bar B is formed or provided at or near each end with lugs or shoulders b b, which strike the ends of said bar I when the piston C approaches near the limits of its travel, and cause said bar I to partake of its movement until either friction-wheel D or E is thrown out of contact with the fixed friction-wh eel O, thereby preventing accidents and injury to the machine.

The `operation of the machine may be briefly described as follows, although it must bc apparent from an inspection of the drawings in connection with the foregoing description: The meat-cylinder K, having been swung to an upright position and filled in the usual manner, (the piston @having been first withdrawn thercfrom,) is secured in its horizontal or working position, as seenin Fig. 2, by the dogs or catches a a. A case having been drawn over the gut-tuben in the usual way, the lever Lis forced by the operator to theleft,bringing the friction-wheel E into contact with the frictionwheel O,which., communicating motion to the several intermediate gears, causes the rack B and piston C to advance, forcing the meat through the tube u into the case,which is thus rapidly drawn off from said tube and lled, the operator regulating the force and rapidity with which the meat is expressed from cylinder K by pressure upon the leverL,or,when both hands are used in the manipulation of the cases on tube 'za-,by the pressure of the foot on the front orleft-hand arm of lever P. By means of the variable speed and force with which the piston C is thus fed forward, controlled by the hand or foot of the operator,

L the breaking of the cases wherever weak places occur in them can be to a great extent prevented, and the stuffing of the cases as perfectly done as by the hand machines. Vhen the piston C approaches the end or bottom of the meat-cylinder K, the shoulder b on rack B strikes the rear end of bar I, forces it forward, and withdraws the friction-wheel E from contact with the wheel O, thus arresting the advance of said rack and piston.

The operator, by forcing the lever L to the right, as seen in Fig. 2, brings the larger and more-rapidly-rotating friction-driver D into contact with the fixed friction-wheel O, which is thus rapidly rotated in the reverse direction and the rack and piston quickly withdrawn from the cylinder K. As said piston emerges from said cylinder the shoulder b on rack B strikes the front `end of bar I3 and throws the friction-wheels D and Oout of contact, arresting the movement of said rack and piston.

The details of my machine may be variously modified without departure from the spirit of l my invention.

The number, size, and arrangement of the gears employed to transmit the variable movement of `the friction-wheel O to the piston C may be changed, any of theknown forms and i arrangements of gearing suitable for that pur.- pose coming within the scope of my invention. Having thus described my invention, what I claim as new, and desire to secure by Letters l Patent, iswj l. The combination of the cylinder K, piston C, arranged to workin said cylinder, a friction-wheel connected by suitable gearing with said piston, and a friction-driver arranged to impart a variable movement, under the control of the operator, to said piston,.substantially as and for the purposes set forth.
